FLUX 3 is Black Forest Labs’ multimodal foundation model, announced July 23, 2026 and currently in Early Access. It jointly learns from images, videos, and audio within a unified architecture built on Self-Flow, their approach for aligning multimodal generation and understanding in the same model. Instead of treating each modality in isolation, FLUX 3 learns a shared representation of the world: how objects hold together, how things move, and how events sound. Capabilities and limits may change during the Early Access rollout. For video, FLUX 3 creates highly diverse clips with native audio up to 20 seconds long in a single generation. All outputs come with synchronized audio generation, including ambient sound, speech, and effects. It supports text-to-video and image-to-video generation, with multi-shot output that chains individual clips into longer sequences and flexible aspect ratios.

  1. You are not using the latest ComfyUI version (Nightly version)
  2. Some nodes failed to import at startup
